' To all whom traag/'concern' Be it known that I, CHARLES KUDERER, a`

citizen of the United States, residing at Pittsburgh,lin the county of Allegheny and State'of Pennsylvania, have invented certain new and useful Improvements in Guards for Lubricating'Devices, of which the following is 'a specification.

This invention 4relates to lubricating de@v vices designed more vparticularly for the 'drive shaft andthe gears of rolling mill tables, and its objectis to provide a novel and improvedstructure of this kindwhich insures the proper lubrication of the gears and the 'shaft bearings. v

The invention comprises a troughin which the drive shaft and the gears are inclosed, said trough having a gland or closure of improved construction which renders trough dustproof and oil tight.

The invention also has: forl its object to l provide a structure which permits the ready removal of the entire trough and the drive shaft Without disturbing the table rollers.

Other objects and advantages of the 1in vention will be :pointed out lin the detailed description appearing hereinafter,y and in forder that the same may be'better under` 'stood, reference is had t0 the accompanying drawings, in whichy Figure 1 is a plan view with parts broken away, showing the application of the'inven- 1 tion; Fig.l 2 is a cross section on the line 2-2 of Fig. 1; Fig. 3 is a section on the line 3 3 of Fig. 1 Fig. 4 isa face view of one of th glands, a ud Fig. 5 is a'vertical section on the line 5 5 of Fig. 4. Q

Referring specifically to the drawings 10 denotes a stand havingbearings 1`1Vfor the journals 12 on one end of the table rollers- 13. On the ends 0f the journals are bevel gears 14 which are in mesh with bevel gears 15 on a drive shaft 16, whereby the rollers are driven from said shaft. The drive shaft and the bevel gears are inclosed in a trough 17 which is of such length as to inclose the drive gears of all the table rollers. As it is not necessatry to an, understanding ofthe invention to illustrate all the rollers, only twp of such are shown in the drawing. The bottom of the trough has webs 18 which are bolted to the stand 10 as indicated at v19. In-

the trough are journal bearings 20 Lfor the drive shaft 16. The top of the trough is provided with a lid orcover 21 which is retrough. Th

the

movable in order that access to the lparts iii-.

closed in the 'trough may be had.'A The lid is in sections, each` sectionv beinga Aflat plate.`V which'seats on top of the trough. Thel plates" are held in placevby cross bars 22 fitting on top thereof over the joint therebetween. the bottom of the plates arecenteriiig pins 23,v and each plate has-a handle 24 to facilitate removal, a handle 25 beingalso provided for the cross bars, Thecross bars are clampedv down atone end by screws 26 carried byfan overhanging supportand lug 27 extending from the rearqwall `28 of the clamped down by bolts 29', Vpiv'oted at 80 to lugs 31 on; the front wally of the trough. The

front ends of thecross bars have. slots 32 to` receive the bolts and upon Ascrewing downv the nuts 33 carried by the bolts the front j ends ofthe bars are clampeddown on the trough.. The pivotalrsupp'ort 'ofthe bolts,

vand the Vslots in the cross bars enable the" Ibolts ,to'beswung down to clear the '.cross' bars, thus releasing the front ends. thereof, and upon backing the screws 26, the plates may be removed. Any one of the plates mayA thus be `readily removed, and it is no t necessary to'remove all the plates if only a certain portionofwthe troughisi to be opened. i

. In therear, wall 28 of the trough are openings 34 so that the gears 14 may enter the trough.y Over each -of these openings is mounted a gland which provides a dustproof and oil tight'closure. This gland comprises top and bottom sections 35 and 36 respectively having opposite semiecircular openings to accommodate the hub of the gear.` The openings have a Babbitt lining 37. The meeting ends of the sections, `on both sides of the openings are connected by a tenonvand-inortise joint, the tenons 38 being on the section 36 and the section 35 having the iiiortisesV 39 to receive the tenons. This joint is continued through the Babbitt lining. By providing a Babbitt lining there is no wear on the gland, and the lining can e other ends ofthe cross bars are gia-na on :the 'buter face lugs 41- which are, s'pac'ed' from'said faeegso, aste comeoppositethe outerfaceof the wall*l 428V. when the gland isvv in place.
